Answer:
500 figures.
Step-by-step explanation:
We know that 185 figures is 37% of her entire collection.
Let c represent the total amount of figures.
Since 185 is 37% or 0.37 <em>of</em> her total collection, we can write the equation:
Remember that the keyword <em>of</em> tells us it's multiplication.
Therefore, to find the number of figures in her total collection, divide both sides by 0.37:
Evaluate. Use a calculator. So:
Sofia's total collection has 500 figures.
Answer:
s = 17 units
Step-by-step explanation:
In triangle ABD,
(AB)² + (BD)² = (AD)² (by Pythagoras Theorem)
=> 8² + 15² = s²
=> 64 + 225 = s²
=> s = 
=> s = 17 units

Answer:
Step-by-step explanation:
the constant drain of water is C:
C= (1000-940)/10 = 6 gallons per minute
after x minutes : 1000- 6x ( water left in the tank after x minutes)
for 5 minutes: 1000-6(5)=970
after 20 min.: 1000-6(20)=880
after 30 min.: 1000-6(30)=820
after 27 min.: 1000-6(27)= 838
the rate of flow of water is 6 gallon per minute
